We’re not able to decide that for you.
As a forums user, all I can say is go for it and hope for the best.
As a member of the helper management team and staff, I can’t give you feedback other than give it 100% effort, and try your best.
I was given some great advice a few years ago when I considered applying for staff on my previous server, which was:
“If you’re meant for staff, you’ll become staff in the end”.
Basically - at the end of the day, only you know if you’re ready to apply or not. After that, it’s out of your control, but at least you’ll know you tried your best!
